Question 1

What happens if I don't replace my main bearings during an engine rebuild?

Accepted Answer

Old or worn main bearings can cause a drop in oil pressure, which can lead to serious engine damage. Replacing them during a rebuild ensures proper lubrication and extends the life of your engine.

Question 2

Are these bearings standard size?

Accepted Answer

This ACL part number is for a 0.50mm / 0.020" undersized bearing set. This means the crankshaft journals must be machined to match the smaller size for proper oil clearance.

Question 3

What else should I replace when replacing the main bearings?

Accepted Answer

When replacing main bearings, it's best practice to also replace the connecting rod bearings at the same time. Also inspect the crankshaft for wear and have it machined if necessary to ensure proper fitment and oil clearance.
